It should be noted that, in the present application, technical features in examples and embodiments may be combined with each other without conflict, and the detailed description in the specific embodiment should be understood as an explanation of the gist of the present application and should not be construed as an improper limitation to the present application.

In the description of the present application, the "up," "down," "top," "bottom" orientations or positional relationships are based on the orientations or positional relationships illustrated in FIG. 5, it being understood that these directional terms are merely used to facilitate the description of the present application and to simplify the description, and are not intended to indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be considered limiting of the present application.

An embodiment of the present application provides a condenser 1, please refer to fig. 3, fig. 5, and fig. 6, a liquid inlet 111a is formed at an upper end of the condenser 1, a liquid outlet 111b is formed at a lower end of the condenser 1, a plurality of mutually isolated condensate flow channels 111c and a plurality of mutually isolated air channels 112 are formed in the condenser 1, and the condensate flow channels 111c and the air channels 112 are mutually isolated, that is, condensate flowing through the condensate flow channels 111c does not enter the air channels 112, airflow flowing through the air channels 112 does not enter the condensate flow channels 111c, condensate in any one of the condensate flow channels 111c does not flow into other condensate flow channels 111c, and airflow in any one of the air channels 112 does not flow into other air channels 112. Each condensate flow passage 111c communicates with the liquid inlet 111a and the liquid outlet 111b, and each air passage 112 extends through opposite ends of the condenser 1. Specifically, the condensate enters the condensate flow passage 111c from the liquid inlet 111a, flows from top to bottom under the action of the gravity of the condensate flow passage, and is discharged from the liquid outlet 111 b; each air duct 112 is formed with an air inlet 112a and an air outlet 112b, the air flow enters the condenser 1 from the air inlet 112a of the air duct 112, and is discharged from the air outlet 112b after flowing through the air duct 112, and the air flow and the condensate carry out heat exchange in the condenser 1, that is, the condensate and the air flow carry out conduction heat transfer.

The specific composition of the condensate is not limited, and may be water or other types of liquids. In the embodiments of the present application, for convenience of description, the condensate is taken as an example for description.

The condenser 1 is used for dehumidifying and cooling the wet and hot air flow, specifically, the wet and hot air flow enters the air duct 112 from the air inlet 112a, the wet and hot air flow exchanges heat with the condensate, the condensate absorbs the heat of the wet and hot air flow, the water vapor in the wet and hot air flow is separated out from the air flow due to the cooling and condensed into water drops, and the water drops flow downwards along the air duct 112 under the action of self gravity and finally flow out of the condenser 1. Thus, the effect of dehumidifying and cooling the humid and hot airflow is achieved, so that the airflow discharged from the air outlet 112b is relatively low-temperature dry airflow after being cooled and dehumidified. It should be noted that the low-temperature drying air flow is relative to the wet hot air flow, and the temperature of the low-temperature drying air flow is lower than that of the wet hot air flow. The low temperature in the embodiment of the present application may be room temperature.

According to a heat transfer formula of heat transfer, the total heat exchange quantity Q is h A T, wherein Q is the total heat exchange quantity, h is a heat exchange coefficient, A is a heat exchange area, T is an absolute value of the temperature difference between air flow and condensed water, and T is heat exchange time. Among the prior art, air current and the condensate among the condenser carry out the convection current in same cavity and conduct heat, the air current that flows in the condenser has one strand, and the air current is whole little with the condensate contact surface, and heat transfer area A is just little, that is to say, total heat transfer volume Q among the prior art is less, then the aqueous vapor that condenses out from damp and hot air current is just few, and it is relatively weak to trade the matter, and condensing efficiency is not high, and the same clothing of stoving just needs longer time, and is corresponding, also needs a large amount of comdenstion water, and it is consuming time to consume water. In addition, in the prior art, because the condensed water and the air flow are not isolated, partial condensed water can be taken away by the flowing of the air flow, and the clothes drying effect is further influenced.

In the condenser 1 of the embodiment of the application, the air flows flowing into the condenser 1 are divided into a plurality of channels through the air channels 112, the condensate flowing into the condenser 1 is divided into a plurality of channels through the condensate flow channels 111c, the air channels 112 and the condensate flow channels 111c are isolated from each other, the heat exchange area A between the condensate and the air flows is increased, and further the total heat exchange quantity Q between the condensate and the air flows is increased. And because the air duct 112 and the condensate flow channel 111c are isolated from each other, the air flow does not directly contact with the condensate, thereby avoiding the phenomenon that the condensate is carried in the air flow flowing out of the condenser 1 and improving the drying effect of the condenser 1 on the air flow. In addition, since the condensate flow channels 111c are isolated from each other, the temperature distribution of the condensed liquid is relatively uniform in any cross section perpendicular to the height direction of the condenser 1, and the condensing effect on the wet hot air flow in each air channel 112 is relatively uniform, so that the temperature distribution of the dry air flow discharged from each air channel is relatively uniform.

The condenser 1 of the embodiment of the present application may be used in any appropriate application. Exemplarily, the present embodiment is described by taking the condenser 1 as an example of application to a laundry treatment apparatus.

Exemplarily, the present embodiment provides a clothes treatment apparatus, please refer to fig. 1 and 2, the clothes treatment apparatus includes a drum assembly 2, an air guide device 3, a liquid guide tube (not shown), and a condenser 1 provided in any embodiment of the present application. The cylinder component 2 is provided with a clothes treatment cavity, an air inlet and an air outlet, the air outlet is communicated with the air inlet 112a, the air guide device 3 is communicated with the air outlet 112b of the condenser 1 and the air inlet of the clothes treatment cavity, one end of the liquid guide pipe is connected with the liquid inlet 111a to guide condensate into the condenser 1, the other end of the liquid guide pipe can be connected with a tap water outlet, and tap water is used as condensate; or can be connected with a condensed water collecting tank, and the recovered condensed water is used as condensed fluid; other approaches are possible and not limiting herein. A fan and a heater are disposed in the air guide device 3.

In the clothes drying process of the clothes processing equipment: the air guide device 3 guides the dry hot air flow into the clothes treatment cavity through the air inlet, in the clothes treatment cavity, the dry hot air flow flows through the surface of wet clothes to perform heat and moisture exchange with the wet clothes, so as to absorb moisture in the clothes and change the moisture into wet hot air flow, the wet hot air flow sequentially passes through the air outlet and the air inlet 112a and then enters the condenser 1, the low-temperature dry air flow is formed after condensation and dehumidification by the condenser 1 and enters the air guide device 3 from the air outlet 112b, the dry hot air flow is formed after heating by the heater, and the dry hot air flow enters the clothes treatment cavity again, so that the continuous and efficient drying of the clothes is realized. It should be noted that the water droplets condensed from the hot humid air stream may flow downstream into the drainage channels of the cartridge assembly 2.

Clothes treatment equipment in this application, the condensing efficiency of condenser is higher, and the time that the same clothing of stoving needs shortens, and the quantity of comdenstion water reduces, has also shortened the clothing time of drying when using water wisely.

In one embodiment, referring to fig. 1 and 2, the barrel assembly 2 includes an inner barrel 21 and an outer barrel 22, the inner barrel 21 is rotatably disposed in the outer barrel 22, and the condenser 1 is connected to the outer barrel 22.

For example, referring to fig. 4, 7 and 8, the condensate flow channels 111c and the air channels 112 are arranged in a staggered manner, that is, at least one condensate flow channel 111c is arranged at a position adjacent to each air channel 112, so that the hot and humid air flow in each air channel 112 can exchange heat with the condensate in the adjacent condensate flow channel 111c, and the heat exchange efficiency between the condensate and the hot and humid air flow is improved.

Specifically, the condensate flow passage 111c and the air passage 112 in the condenser 1 are arranged in a staggered manner in various ways, and are not limited herein. For example, the air ducts 112 may be distributed in a multi-layer annular array on the cross section of the condenser 1 perpendicular to the direction of the air ducts 112, or the air ducts 112 may be distributed in a rectangular array on the cross section, etc. When the air ducts 112 are distributed in a multi-layer annular array, the condensate flow channels 111c may be disposed between two adjacent air ducts 112 on the same annular layer, or may be disposed annularly between the air ducts 112 on two adjacent annular layers, and the distances and distribution positions of the condensate flow channels 111c arranged annularly are also various, as the case may be. In addition, the air ducts 112 may also be distributed in multiple rows or multiple columns, and the air ducts 112 between two adjacent rows or two columns are arranged in a staggered manner, in which case the condensate flow channel 111c may be disposed between two adjacent air ducts 112 in the same row or column, or between two air ducts 112 in adjacent rows or columns. The condensate flow passage 111c may be disposed between two adjacent air passages 112, and one air passage 112 may be disposed every two or more condensate flow passages 111 c.

Illustratively, a plurality of condensate flow channels 111c are disposed about a single air chute 112, which can facilitate more efficient heat exchange with the air flow within the air chute 112.

For example, referring to fig. 7 and 8, the air ducts 112 are distributed in a rectangular array on the cross section of the condenser 1 along the direction perpendicular to the extending direction of the air ducts 112, and the condensate flow channels 111c are disposed at the center of the quadrangle formed by the four adjacent air ducts 112. The arrangement can fully utilize the arrangement gap of the air channels 112, so that the condenser 1 has a compact structure; and the plurality of condensate flow channels 111c are uniformly surrounded on the periphery of the air duct 112, which is beneficial to improving the heat exchange coefficient h between the two. In addition, on the premise that the cross-sectional area of the condenser 1 is fixed, the arrangement mode is more favorable for the arrangement of the air duct 112 and the condensate flow channel 111c, and a larger heat exchange area between the air duct 112 and the condensate flow channel is realized.

It will be appreciated that in some embodiments, the air inlet 112a is located at the lower end of the condenser 1 and the air outlet 112b is located at the upper end of the condenser 1, and the air flow is in the opposite direction to the condensate flow. In another embodiment, the air inlet 112a is located at the upper end of the condenser 1, and the air outlet 112b is located at the lower end of the condenser 1, in which case the air flow is in the same direction as the condensate flow. It is to be understood that the arrangement positions of the intake port 112a and the exhaust port 112b are not limited thereto.

In one embodiment, referring to fig. 5 and 6, the air inlet 112a is located at the lower end of the condenser 1, and the air outlet 112b is located at the upper end of the condenser 1. It will be appreciated that the condensate is continuously heat exchanged with the air stream as it flows from the upper end to the lower end of the condenser 1 by its own weight, and therefore, the temperature of the condensate flowing into the condenser 1 is gradually increased until the temperature of the condensate reaches the highest at the liquid outlet 111 b. The air flow flows from the lower end to the upper end of the condenser 1, the condensate flows from the upper end to the lower end of the condenser 1, the air flow flowing into the condenser 1 firstly exchanges heat with the condensate with higher temperature, and after the temperature is reduced by a part, part of the water vapor is condensed into water drops. Before flowing out of the condenser 1, the water vapor exchanges heat with the condensate with lower temperature, the temperature is reduced again, and the water vapor continues to be condensed into water drops, so that the water vapor in the air flow is favorably condensed into water drops more. That is, the flow direction of the gas stream is opposite to the flow direction of the condensate, which further improves the efficiency of the heat exchange between the condensate and the gas stream.

The plurality of air channels 112 may be arranged in parallel, or may be arranged in a crossed manner at the same or different angles, for example, the plurality of air channels 112 are arranged in a spiral manner. For example, in an embodiment, referring to fig. 5 and 6, the plurality of air ducts 112 are arranged in parallel, so that the condenser 1 has a simple structure, is convenient to manufacture, and reduces the production cost.

The plurality of condensate flow channels 111c may be arranged in parallel, or may be arranged at the same or varying angles in a crossed manner, for example, the plurality of condensate flow channels 111c may be arranged in a spiral manner. For example, in an embodiment, referring to fig. 5 and fig. 6, the plurality of condensate flow channels 111c are disposed in parallel, so that the condenser has a simple structure, is easy to manufacture, and reduces the production cost.

The condensate flow passage 111c and the air passage 112c may be arranged in parallel, or may be arranged to intersect at the same or a varying angle. In an embodiment, the condensate flow channel 111c and the air duct 112 are arranged in parallel, which is beneficial to the arrangement of the condensate flow channel and the air duct in the condenser 1, and improves the compactness of the structure of the condenser 1.

The bottom end surface of the condenser 1 can be a plane or a certain radian. Exemplarily, in one embodiment, the bottom surface of the condenser 1 is an arc surface adapted to the outer drum 22 of the clothes treating apparatus. At this time, the condenser 1 is completely located outside the outer cylinder 22, and the bottom end surface of the condenser 1 is matched with the outer surface of the outer cylinder 22 of the clothes treatment device, so that after the condenser 1 is installed on the outer cylinder 22 of the clothes treatment device, the condenser 1 and the outer cylinder 22 keep good fit and are compact in structure.

The communication manner between the plurality of condensate flow passages 111c and the liquid inlet 111a is not limited. For example, referring to fig. 5 and 6, a liquid dividing cavity 113a is formed in the condenser 1, the liquid dividing cavity 113a is communicated with the liquid inlet 111a, the water inlets of the liquid dividing channels 111c are formed on the wall surface corresponding to the liquid dividing cavity 113a, and the condensate entering the liquid dividing cavity 113a from the liquid inlet 111a can flow into the liquid dividing channels 111c corresponding to the water inlets through the water inlets. Specifically, the condensate flows into the liquid distribution cavity 113a through the liquid inlet 111a, and then flows into the condensate flow channels 111c through the water inlets of the condensate flow channels 111c, and the liquid distribution cavity 113a can buffer the condensate from the liquid inlet 111a, so that the condensate can flow into the condensate flow channels 111c relatively uniformly, the condensate is distributed relatively uniformly in the condenser, and the heat exchange effect is improved.

The specific shape of the liquid-separating chamber 113a is not limited as long as the liquid inlet 111a and the water inlets of the respective condensate flow paths 111c can be communicated with each other. In addition, the air duct 112 sealingly penetrates the liquid-passing chamber 113a to penetrate opposite ends of the condenser 1.

The communication manner between the plurality of condensate passages 111c and the liquid outlet 111b is not limited. In an exemplary embodiment, a liquid collecting chamber 114a is formed in the condenser 1, the liquid collecting chamber 114a is communicated with the liquid outlet 111b, the water outlet of each condensate flow passage 111c is formed on a corresponding wall surface of the liquid collecting chamber 114a, and the liquid collecting chamber 114a is capable of collecting the condensate from each condensate flow passage 111c and discharging the collected condensate from the liquid outlet 111 b. Specifically, the condensate that has entered the condenser flows into the liquid collection chamber 114a through the water outlets of the respective condensate flow channels 111c, joins in the liquid collection chamber 114a, and is discharged out of the condenser 1 through the liquid outlet 111 b. The provision of the liquid collection chamber 114a further facilitates the collection and discharge of the condensate out of the condenser 1.

The specific shape of the liquid collecting chamber 114a is not limited as long as the collected condensate can be made to flow toward the liquid outlet 111b, and the air duct 112 sealingly penetrates the liquid collecting chamber 114a to penetrate the opposite ends of the condenser 1.

In one embodiment, referring to fig. 3, 5 and 6, the bottom wall of the liquid collecting chamber 114a is an inclined surface, and the liquid outlet 111b is located at the lowest position of the inclined surface, so that the inclined surface can guide the collected condensate to the liquid outlet 111 b. Specifically, after the condensate enters the liquid collecting cavity 114a, the condensate flows downwards along the bottom wall surface of the liquid collecting cavity 114a under the action of self gravity, and since the liquid outlet 111b is located at the lowest position of the inclined surface, the condensate in the liquid collecting cavity 114a finally flows to the liquid outlet 111b under the guidance of the inclined surface and is discharged from the liquid outlet 111b, so that the outflow of the condensate in the liquid collecting cavity 114a is facilitated, and the heat exchange efficiency of the condensate and the airflow is prevented from being influenced due to the accumulation of the condensate in the condenser 1.

It should be noted that the bottom wall surface of the liquid collecting cavity 114a may be a downward inclined plane, a curved surface with a certain curvature, or a curved surface with corrugations, which is not limited herein, and it is only necessary that the water in the liquid collecting cavity 114a can flow to the liquid outlet 111b under the flow guiding effect of the bottom wall surface.

It will be appreciated that the construction of the condenser 1 and the manner of formation thereof is not limited. For example, the condenser 1 may be a column or a polyhedron having an irregular shape. The condenser 1 can be formed by connecting various parts into a whole in a clamping, welding and other modes, and can also be formed by integral injection molding.

Illustratively, in one embodiment, the condenser 1 includes a column 11, each air duct 112 extends through the column 11 in the up-down direction, each condensate flow passage 111c is hermetically disposed in the column 11, and the liquid inlet 111a and the liquid outlet 111b are disposed on the circumferential surface of the column 11, so as to prevent the liquid inlet 111a and the liquid outlet 111b from interfering with the condensate flow passage 111c and the air duct 112, and to facilitate compact arrangement of the condensate flow passage 111c and the air duct 112 in the column 11.

The cross-sectional shape of the column 11 in the direction perpendicular to the up-down direction is not limited, and may be polygonal, elliptical, circular, or the like. For example, referring to fig. 3 to 8, the cross-sectional shape of the column 11 perpendicular to the up-down direction is circular, that is, the column 11 is cylindrical, the air channels 112 are uniformly distributed on the circular cross-section of the cylindrical column 11, the condensate flow channels 111c and the air channels 112 are uniformly distributed at intervals, and the condensate flow channels 111c and the air channels 112 are also circular on the cross-section of the column 11, under the condition that the cross-sectional area of the column 11 is the same, a greater number of condensate flow channels 111c and air channels 112 can be arranged, and the flow capacity of each air channel 112 and each condensate flow channel 111c is stronger; in addition, the condensate flow channel 111c and the air channel 112 in the condenser 1 can be arranged more closely, and the structural compactness of the condenser 1 is improved.

In one embodiment, the condenser 1 includes a cylinder 12, the cylinder 12 is surrounded at the edge of the top side of the column 11, and the air flow from each air duct 112 exits the condenser 1 through the cylinder 12. The air flows flowing out of the air ducts 112 are mixed in the cylinder 12 to improve the uniformity of the temperature and the flow rate of the air flow entering the air guide device 3. The cylinder 12 can be integrally formed with the cylinder 11, and can also be connected to the cylinder 11 in a clamping manner, a welding manner and the like, and the condenser 1 can be conveniently mounted on the air guide device 3 by arranging the cylinder 12.

In one embodiment, the upper end of the barrel 12 is formed with a slot 12a with an upward opening, and the slot 12a surrounds the edge of the top end of the barrel 12. By arranging the clamping groove 12a, the air guide device 3 can be clamped in the clamping groove 12a and supported on the condenser 1, so that the condenser 1 is convenient to mount. It will be appreciated that, in order to avoid air leakage, a sealing ring may be provided in the slot 12a to improve the sealing at the connection between the air guiding device 3 and the condenser 1.

It should be noted that the second rib plate 114b may be formed on the pillar body 111, or may be formed on the second end cover 114, or may be formed partially on the second end cover 114, and partially formed on the pillar body 111, which is not limited herein.

It should be noted that the shapes of the first end cap 113 and the second end cap 114 are not limited, and only need to be capable of communicating with the liquid inlet 111a or the liquid outlet 111b and communicating with the condensate flow channel 111c, and the joint between the first end cap 113 and the column body 111 has certain sealing performance.

It will be appreciated that in embodiments where the column 11 includes both the first end cap 113 and the second end cap 114, each of the condensate flow passages 111c extends through both the upper and lower ends of the column body 111.

The shape of the bottom end surface of the condenser 1 is different according to the installation manner of the condenser 1 and the outer cylinder 22 of the clothes treatment apparatus, when the lower end of the condenser 1 is installed on the outer cylinder 22 in a manner of being inserted into the outer cylinder 22, the bottom end surface of the condenser 1 can be any suitable shape, and when the bottom end surface of the condenser 1 is installed on the outer surface of the outer cylinder 22 in a fitting manner, the shape of the bottom end surface of the condenser 1 is required to be matched with the outer shape of the outer cylinder 22. In the embodiment where the column 11 includes the second end cap 114, the bottom end face of the condenser 1 is the lower surface of the second end cap 114. Specifically, in one embodiment, the lower surface of the second end cover 114 is an arc surface adapted to the outer drum 22 of the clothes treating apparatus, so that the condenser 1 can be well attached to the outer drum 22 of the clothes treating apparatus after being mounted thereon.

It will be appreciated that the upper surface of second end cap 114 is the bottom wall surface of liquid collection chamber 114 a.

It should be noted that, because the shape of the upper surface of the second end cap 114 may be various, the shape of the lower surface may be adapted to the outer tub 22 of the laundry treating apparatus. That is, the shapes of the upper and lower surfaces of the second end cap 114 are not necessarily the same, and thus, the wall thickness of the second end cap 114 is not necessarily uniform.

The condenser 1 may be disposed at any suitable position outside the outer tub 22, for example, when the laundry treating apparatus is a pulsator type laundry treating apparatus, the condenser 1 may be disposed at any side of the drum assembly 2 in the circumferential direction.

In the embodiment where the laundry treating apparatus is a drum-type laundry treating apparatus, the condenser 1 may be disposed at the rear side of the drum assembly 2 in the axial direction of the inner drum 21, or may be disposed at the outer portion of the circumferential direction of the inner drum. For example, referring to fig. 1 and 2, the bottom end surface of the condenser 1 is an arc surface matched with the outer surface of the outer drum 22 of the drum assembly 2, so that the condenser is attached to the circumferential outer surface of the outer drum, and thus the overall structure of the clothes treatment apparatus is more compact.

Wherein, the inner cylinder 21 can be a non-hole type inner cylinder 21 or a hole type inner cylinder 21. When the inner cylinder 21 is a perforated inner cylinder 21, water is contained by the outer cylinder 22, and when the inner cylinder 21 is a non-perforated inner cylinder 21, water is contained by the inner cylinder 21, that is, water can be contained in the inner cylinder 21 and clothes can be contained in the inner cylinder 21, water in the inner cylinder 21 does not enter the outer cylinder 22 in the washing process, and water can be drained through the outer cylinder 22 in the draining process.
